The Loretto Chapel in Santa Fe, New Mexico, USA, is a former Roman Catholic church that is now used as a museum and a wedding chapel.
It is known for its unusual helix-shaped spiral staircase (the "Miraculous Stair"). The Sisters of Loretto credited St. Joseph with its construction.
It has been the subject of legend, and the circumstances surrounding its construction and its builder were considered miraculous by the Sisters of Loretto
Loretto Chapel is best known for its "miraculous" spiral staircase, which rises 20 feet (6.1 m) to the choir loft while making two full turns, all without the support of a newel or central pole.
The staircase is built mostly out of wood and is held together by wooden pegs and glue rather than nails or other hardware.
The inner stringer consists of seven wooden segments joined together with glue, while the longer outer stringer has nine segments.
